Went out and disconnected the line to the brake booster. It works opposite of how I thought it does. The line to the brake booster pulls air from the booster, a massive amount of air. So the engine isn't losing air, it's getting air added to it.
So you have the venturi tube adding air and the AOS adding air after the MAF sensor, how does the ECU actually know the amount of air going into the engine?
